For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of switching mechanism of automatic change-over, comprise base plate, described base plate has a circular hole, motor is provided with below described circular hole, described machine shaft is provided with disk, described disk is positioned at above base plate, described disk is provided with circular arc guide groove, described circular arc guide groove two ends are respectively provided with a projection, the left side of described backplate surface is provided with a left sliding axle, the right side of described backplate surface is provided with a right sliding axle, described left sliding axle is provided with a left slide plate, described left slide plate is provided with a left rocking arm, described right sliding axle is provided with a right slide plate, described right slide plate is provided with a right rocking arm, the right side on described left slide plate surface has a slotted hole, described left slide plate surface is provided with a catch below slotted hole, a left groove is had below the slotted hole on described left slide plate surface, the left side on described right slide plate surface has a slotted hole, described right slide plate surface is provided with a catch below slotted hole, a right groove is had below the slotted hole on described right slide plate surface, described backplate surface is positioned at above left slide plate and right slide plate and is provided with a baffle plate, a transducer is provided with in the middle of described left slide plate and right slide plate, described transducer is connected with motor, described transducer bottom is each side provided with a contact chip, described transducer both sides are respectively provided with a spacer, described spacer is connected with base plate by cylinder nail, described cylinder nail is through slotted hole.
Further, described catch is connected with left slide plate by screw.
Further, described catch is connected with right slide plate by screw
Further, described baffle plate is connected with base plate by screw.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, when can not power for load equipment when using power supply to go wrong, electric machine rotation, disk in drive motor rotating shaft, disk drives circular arc guide groove to rotate, thus the projection on circular arc guide groove drives left slide plate and right slide plate to move up and down, make the left rocking arm of motor both sides and right rocking arm do rightabout movement, drive the switch of disconnecting link with closed; There is structure simple, easy to use, prevent power cut-off, the advantages such as use safety.
